The Ken-Tool 8-in-1 Wrench Metric version, delivers strength, versatility and convenience in a 190mm, 350gm slim-profile tool. The wrench is fabricated from cold-forged, high-strength vanadium steel alloy. At the heart of the wrench is the “Slide-Twist-Slide” design to quickly change wrench sizes. To change the size, the user slides the carrier to the center, twists it 180 degrees and slides back to lock in place. This metric version (#35776) has 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, 16mm and 17mm sizes. The “Stud-Thru” feature permits studs and bolts to pass through the opening. The 12-point closed box design needs only a 30-degree re-engagement arc for tight clearances.
